  2. Time-of-flight diffraction ultrasonics - Wikipedia

    en.wikipedia.org/wiki/Time-of-flight_diffraction...

    Time-of-flight diffraction (TOFD) method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington [1] in 1975 which paved the way for TOFD. Later works on this technique are given in a number of ...

  3. Time of flight - Wikipedia

    en.wikipedia.org/wiki/Time_of_flight

    Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate).

  4. Time-of-flight detector - Wikipedia

    en.wikipedia.org/wiki/Time-of-flight_detector

    A time-of-flight (TOF) detector is a particle detector which can discriminate between a lighter and a heavier elementary particle of same momentum using their time of flight between two scintillators [1]. The first of the scintillators activates a clock upon being hit while the other stops the clock upon being hit.

  5. Time-of-flight camera - Wikipedia

    en.wikipedia.org/wiki/Time-of-flight_camera

    Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.

    Time of flight, a principle of several scientific methods Time-of-flight camera, a camera system that analyzes time of flight of the light it captures, to resolve depth; Time-of-flight mass spectrometry uses the time of flight of an ion in the gas phase to resolve its mass-to-charge ratio; Tetralogy of Fallot, a congenital heart defect

    The Pentagon has failed its annual financial audit for the seventh year in a row. This means the Department of Defense (DOD) has failed every single audit it has been subjected to, but officials ...

  9. Optical lattice - Wikipedia

    en.wikipedia.org/wiki/Optical_lattice

    A common observation technique is time of flight (TOF) imaging. TOF imaging works by first waiting some amount of time for the atoms to evolve in the lattice potential, then turning off the lattice potential (by switching off the laser power with an AOM). The atoms, now free, spread out at different rates according to their momenta.
